PUMP.

SPECIFICATION forming part of Letters Patent No. 475,895, dated May 31, 1892.

Application tiled February 25,1891. Serial No. 382,798. (No model.)

To all whom, t may concern.-

Be it known that I, ENGELBERT J. SCHIL- LER, a citizen of the United States, residing at Grant, in the county ot' Perkins and State of Nebraska, have invented a new and useful Pump, of which the following is a specification.

This invention relates to pumps or waterelevating devices; and it has for its object to provide a device of this class which shall be simple, durable, and efficient, and which may be operated with the least possible expenditure of power.

The invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, Figure 1 is a vertical sectional view of a water-elevating device constructed in accordance with my invention. Fig. 2 is a transverse sectional view taken on the line 2 2 in Fig. 1.

Like numerals of reference indicate like parts in both iigures.

1 designates the pump-cylinder, which extends downwardly from a box or casing 2,10- cated near the bottom of a well, and which is supported upon said cylinder to form a receiving and distributing reservoir from which the water is elevated to the top of the well, as described. Said cylinder is provided at its lower end with an upwardly opening check-valve 3, and it has a valved piston or plunger 4,the stem 5 of which extends upwardly into the box or casing. The latter is provided at its upper and lower ends with packing-boxes 6 and 7, through which extends a tube 8 in a parallel vertical plane with said cylinder, the lower end of which is closed by a cap 9. The tube S is provided with side openings 10, which are formed in the portion of said tube which is always within the box or casing 2, and suitably attached to said tube within said box or casing is the upper end ot the plunger-stem 5, the tube being preferably provided with a laterally-extending arm or bracket, to which the said plunger stem may be conveniently connected. The upper end of the tube 8 is connected by a sleeve or coupling 11 with an upwardly-extending tube 12, only a portion of which is shown in the drawings, and the upper end of which is to be provided with or connected with a suitable dischargespout. In the said tube 8, near its upper end, is alsoflocated an upwardly-opening check-valve I,14.

The operation of invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. The pump is operated by imparting a reciprocating motion to the tube S. On the downstroke the valved plunger 5 passes the water above the check-valve ,said water being on the succeeding upstroke raised into the box or casing. On the following downstroke water from within the casing will pass through the slots or openings 10 in the sides of the tube 8 into said tube, where it will pass the check-valve 14, to be raised on the succeeding upstroke. The box or casing 2 is to remain stationary at the bottom of the well, as will be readily understood. It is obvious that the downstroke of the tube 8 and its upward extension, with the water contained therein, will take place very easily on account of the weight of the same, and inasmuch as there is no resistance to the lower end of said reciprocating tube, as in ordinary plungers, to assist the upstroke I propose to attach lto the lever or handle by means of which the pump is operated, and which is designated by 15, a weight 16, which shall be sufficiently heavy to balance the said tube with the water contained therein. Inasinuch as this weight to be overcome would be considerable in wells of great depth, I propose to dig a hole, as 17, adjacent to the pump, said hole or excavation being of sufficient dimensions to accommodate a box 18, which is suitably connected with the pump handle and weighted by means of sand, gravel, or the like. This arrangement is simple and inexpensive and permits the desired adjustment to be easily made by taking from or adding to the weight until the parts are properly balanced. It

will thus be seen that by this device the water may be raised from wells without regard to the depth of the same with the least possible expenditure of power. It can also be readily seen that by extending one plunger-pipe through the box or casing it leaves no opportunity for the water contained in IOO said box or casing to interfere with a free downward stroke, and by such construction the entire Weight of the water contained in the pipe is gained without the friction caused by the surging of the Water in the pipe, as is contended With and is the objectionable feature of pumps having their hollow plungers or cylinders Working directly Within the ciprocating tube extending entirely through said box and packing-boxes in the same in a parallel plane to said pump-cylinder and provided With a closed lower end working below the box, a series of lateral Water-inlets opening into said box or casing, and an upwardly-opening valve near its upper end, a valved plunger Working in said cylinder and connected with said tube Within the box or casing and through which the Water gently passes into the tube elevating the same and reciprocated thereby, a discharge-pipe connected with said tube, and means for reciprocating the tube, substantially as set forth.

In testimony that I claim the foregoing as my oWnIhave hereto affixed my signature in the presence of tvvo Witnesses.
